How Is Gold Formed? Origins and Process

06/05/2019· In these events, gold formed during the r-process. Gold sank to the Earth's core during the planet's formation. It's only accessible today because of asteroid bombardment. Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It's easiest for scientists to transmute gold by bombarding the heavier element mercury and producing gold

Processing, smelting and refining gold World Gold

More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding
